You don't need Adobe Illustrator to open or convert an .AI file — you can turn it into a PNG or JPG for free in your browser. Illustrator files are usually PDF-compatible under the hood, which is what makes this possible without any Adobe software or subscription.
Can you open an AI file without Illustrator?
Often, yes. Most .AI files are saved with PDF compatibility, so they can be rendered without Illustrator. That's how a browser tool can open the artwork and export it as a standard image — no monthly subscription just for a one-off export.
How to convert AI to PNG or JPG
Convert AI to PNG for a transparent-capable image, or AI to JPG for a smaller flat one. It runs in your browser, so the file isn't uploaded. PNG is the right choice for a logo because it keeps transparency; JPG is fine for a flat preview where file size matters.
PNG or JPG — which should you pick?
PNG for logos, icons, and anything with transparency or sharp edges; JPG for a flat, photo-like export. A logo almost always wants PNG. If you're unsure, PNG vs JPG vs WebP breaks it down.
What you lose converting AI to PNG
You're going from vector to raster, so the PNG is fixed at whatever resolution you export — it won't scale up sharply afterwards. Export at the largest size you'll realistically need, and keep the original .AI as your master for future edits.
When a browser tool can't open it
A few .AI files are saved without PDF compatibility, or use effects that don't render outside Illustrator. In that case you'll need Illustrator (or its free trial) to re-save the file with PDF compatibility first. For the format background, see vector vs raster.
